Probabilistic MRI Tractography of the Optic Radiation Using …
WebThe optic radiations are predominantly supplied by the posterior and middle cerebral arteries1 and the AChA.6 Inferior fibres, known as Meyer’s Loop,6 travel to the temporal lobe, while the superior and central nerve fibre bundles travel to the parietal lobes.1 The termination of optic radiations is located in the visual striate cortex (V1 ... WebApr 13, 2010 · The human visual system comprises elongated fiber pathways that represent a serious challenge for diffusion tensor imaging (DTI) and fiber tractography: while tracking of frontal fiber bundles may be compromised by the nearby presence of air-filled cavities, nerves, and eye muscles, the anatomic courses of the three main fiber bundles of the … rds spla licensing
